My invention relates to a central control means of Corliss engines, such as C. D is designed to be utilized in the operation of a raised platform upon which the operator of cane mills, and has for its object to employ the cane milling mechanism is positioned. E a relatively simple device which makes it posis a drum control for the Corliss engines C,

This operator can readily and close the valve G which admits steam to the quickly increase or diminish the speed of the engines. fordrivingthe cane carrier. cane carrier, or entirely stop the same, as It will be noted that the lower end'l of the is well as increase or diminish the speed of the control rod F is screw-threaded and has upvarious crushers and mills in the tandem, or per and lower stops 2 and 3, respectively, poentirely stop the same, as may be desired or sitioned thereon. Between these steps spe necessary in order to grind the maximum cacial nut 1 is placed on the screw-threaded pacities and overcome the possibility of choklower end 1, to which nut is attached one end ing one of the mills of the series in the tan of hell crank 5. To the other end of the bell dem. crank 5 a link 6 is pivoted, which in turn is Another feature of my device is that it perfastened to another bell crank 7. 8 desigmits the operator to note the passage of any nates a rod also pivoted to the bell crank 7 bulky forei n material through the cane mills which controls the opening or closing of the Z0 and to quickly shut down the operation of valve G.

The drum control E is pro mulators. After the foreign material has vided with a flexible cable H which, as noted been removed from the mill tandem the mills in Fig. I, passes down beneath the platform may again be started into operation by the Dover aseries of'sheaves I to the controlling s0 operator. device for the Corliss engines C. as

In order to make it possible to control the It will be noted by reference to Figs. II, speed of the Corliss engines which drive the III and IV that the flexible cable H is conmill tandem I have provided a simple device nected to a spring 9 so that some elasticity in which makes it possible for the operator, conthe operation of said cable may be provided veniently positioned, to control the speed of for. To the upper end of the spring 9 a chain the engine by hand independently of the reg- 10 is secured which passes over a sheave J ular fiyball governor which automatically and is fastened to a link 11, which link in controls the speed of the engine when runturn is secured to a doublearm 12.

Fig. IV is a detail View taken on line 17 is a spring mounted on said rod 15 between IVIV, Fig. III. a nut 18 threaded upon the outer end of said In the drawings, A designates a cane mill arm 15"and one side of the free end of the purpose of this spring 17 is to securely hold the double arm 12 in operative position so that said arm may be at all times under the control of the fly ball governor K.

19 is av weight mounted on a rod 20 which is positioned on the rock shaft 13. 21 is a rod which connects with the fly ball governor K through the pin 22. The purpose of this weight is to determine the speed of the Corliss engines when automatically controlled by the fly ball governor K. 23 is a governor column mounted on the side of the engine frame C. 24 and 25 are governor connecting rods which are pivotally secured at one end to the double arm 12 and control admission of and the cutting off of the steam into the Corliss engine cylinders. As this mechanism and its associated parts about the engine constitute no part of my present invention, I will not refer to it in any greater detail. 26 is a counterbalance weight to assist in pulling the double arm 12 back to normal position.

It will be noted that when the operator turns the drum E to put a pull on the flexible cable II the lower end of the double arm lever 12 is moved, which moves the upper end of said double arm lever in a direction opposite to the movement of the lower end thereof, thereby compressing the spring 17. This movement of the double arm lever moves the governor connecting rods 24 and 25 to diminish the amount of or completely shut off steam to the Corliss engines C. Vhen the operator moves the drum E to permit the flexible cable H to return to its normal position. the double arm lever 12 is moved back to the normal position shown in Fig. II b virtue of the spring 17 and the eounterba ance weight 26. It is evident that the amount of movement of the double arm lever 12 may be independently controlled by the operator through the movement of the drum E, so that if he wants to slow up or stop the Corliss engines C he may quickly do so by the amount of movement of the drum E. lVhen the desired speed of the engine has been reached the operator ceases to rotate the drum E. If he desires to stop the Corliss engines completely he rotates the drum E sufiiciently to entirely cut off the admission of steam to the engines C. As soon as the drum E is rotated to permit the spring 17 and the counterbalance weight 26 to return the double arm lever 12 to its normal position, the engines will again operate under the automatic control of the fly ball governor K.

I claim:

1. In a device of the character described, an engine having means for regulating the speed thereof, a device for controlling the speed of said engine, said device comprising a double arm loosely mounted upon a shaft, one end of said double arm being connected to a device located on an operators platform, a single arm keyed to said shaft, :1. rod connected to one end of said double arm and extended through an opening in said single arm, a spring interposed between the free end of said single arm and the free end of said rod for restoring the double arm to normal position when the pull on said double arm is released, and elements for connecting the ends of said double arm to the speed-regulating means of said engine.

2. In a device of the character described, an engine having means for regulating the speed thereof, means for manually controlling the speed of said engine, said means consisting of a double arm loosely mounted upon a shaft, one end of said double arm being connected to a controlling device positioned on an operators platform, a rod pivotally connected to the other end of said double arm, a single arm keyed to said shaft, said rod passing through an aperture in the free end of said single arm, a spring mounted upon said rod and adapted to contact with the side of the free end of said single arm, away from the end of said double arm, and adapted to normally hold said double arm out of operative position and to restore said double arm to inoperative position when the device on the operators platform is released after causing the double arm to move into position to lessen the speed of the engine, and elements for connecting the ends of said double arm to the speed-regulating means of said engine.

In testimony that I claim the foregoing I hereunto afiix my signature.

MICHAEL B. MENNIGES.
